Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, Volume 13, Issue 19, 2 April 2026.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Parasitic Infections and Associated Cognitive Outcome Among School‐Aged Children in Africa: A Systematic Review

Brain and Behavior, Volume 16, Issue 4, April 2026.
Parasitic infections like schistosomiasis, soil‐transmitted helminths, and malaria can impair nutrient absorption, oxygen supply, and brain function, leading to memory deficits, attention deficits, reduced intelligence quotient, weak academic performance, and motor or executive deficits.

Verification of a Fluid–Structure Interaction Model for Aortic Stenosis Through Comparison With In Vitro Experiments

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.
A patient‐specific Fluid–structure Interaction (FSI) model of aortic stenosis was verified against in vitro experiments using a mock‐loop circulatory system with patient‐specific calcified and non‐calcified valve models under varying flow conditions. The in vitro experiments were replicated in the FSI model.

Mouse Vocal Fold Permeability In Vivo: Effects of Novel Low‐Tech Injury and Instillation Methods

The Laryngoscope, Volume 136, Issue 4, Page 1846-1857, April 2026.
Improving experimental mouse vocal fold injury and instillation approaches is necessary to advance preclinical models of laryngeal disease. We have successfully repurposed low‐tech, quick, and reliable injury and instillation methods established in respiratory research. Using these methods, we show that murine vocal fold epithelium is inherently highly

Designing 3d Transition‐Metal Doped g‐C3N4 Monolayer for Enhanced Bifunctional Oxygen Evolution/Reduction Reactions Activity: Defect Physics and Constant‐Potential Study

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Graphitic carbon nitride (g‐C3N4) doped with 3d transition metals (3d‐TM@g‐C3N4) has gained attention as a noble metal‐free alternative for oxygen evolution and reduction reactions (OER/ORR). Yet the key mechanisms driving its performance remain debated, especially across different charge states.

Comprehensive Characterization of Water Group Ion Composition and Distributions in Saturn's Magnetosphere With Cassini Plasma Spectrometer Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Saturn's magnetosphere is continuously supplied with neutrals from the Enceladus plume and the icy rings, which undergo ionization and charge‐exchange to form a complex water‐group plasma environment. While the Cassini Plasma Spectrometer (CAPS) instrument has provided extensive compositional information, detailed separation of individual ...

Function spaces for decoupling

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract We introduce new function spaces LW,sq,p(Rn)$\mathcal {L}_{W,s}^{q,p}(\mathbb {R}^{n})$ that yield a natural reformulation of the ℓqLp$\ell ^{q}L^{p}$ decoupling inequalities for the sphere and the light cone. These spaces are invariant under the Euclidean half‐wave propagators, but not under all Fourier integral operators unless p=q$p=q$, in ...

Glycosomal Phosphoenolpyruvate Carboxykinase CRISPR/Cas9‐Deletion and Its Role in Trypanosoma cruzi Metacyclogenesis and Infectivity in Mammalian Host

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Effects of PEPCK deficiency in Trypanosoma cruzi bioenergetics and life stages. ABSTRACT Trypanosoma cruzi, the causative agent of Chagas disease, possesses glycosomes—unique organelles that house key metabolic enzymes, several of which are promising therapeutic targets.
